title: New quantified echographic features of normal kidney. Hydronephrosis classification.
abstract: During a period of three months, 400 patients with normal kidneys were examined by ultrasound. An evaluation of 14 parameters was made including renal volume (RV), the correlation RV-weight, RV-height, and RV-age of the patients, the quantitative measurement of the renal parenchyma, and the influence of hydration and bladder distension on the sonographic diagnosis of hydronephrosis. In 40 cases, comparison with an additional contrast urography study permitted us to obtain the radiographic magnification index. We present 10 figures including measurement of the absolute parenchymal thickness, parenchymo-sinusal ratio, pyelocalyceal distension and we illustrate the four grades of our hydronephrosis classification.
